Abstract

The efficiency of fiber impregnation with a polymer melt is one of the most important components that make up the quality of the UD-prepregs and, subsequently, parts made of them. If thoroughly formulated, the mathematical impregnation model could assist to find the most suitable parameters to enhance the impregnation. Consequently, the investigation of the fiber bundle impregnation with the high-viscosity thermoplastic resin melt by pultrusion with impregnation die is represented. An approximate one-dimensional mathematical model of roving impregnation during pultrusion through an impregnation die which considers the polymer melt leakage into fiber bundle is established. The maximum total impregnation depth of fiber bundle depending on the various values of the pulling speed and the fiber tension is calculated. The results show that the calculations of the impregnation depth are hinge on the leakage consideration, as well as on pulling speed and tension.
